PolymarketCancelFailureCode: type: string enum: - STILL_SUBMITTING - ALREADY_COMPLETED - VENUE_DECLINED - MARKET_UNRESOLVED - UNCONFIRMED description: >- Why an order was not cancelled. STILL_SUBMITTING: the order is being placed and has no venue handle yet, so retry shortly. ALREADY_COMPLETED: it filled instead of cancelling. VENUE_DECLINED: Polymarket refused, usually because the order matched first; see message. MARKET_UNRESOLVED: the order's market is not known here, so a market-scoped cancel could not decide whether it was in scope; cancel it by id or repeat without a market. UNCONFIRMED: the cancel could not be confirmed, so the order may or may not still rest; retry. ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
